To (all 1.0700777, it mmu concern:

- Beit known that I, GUssER EVANOVITCH, a citizen of the United Statesof America, re siding at 31 Museum street, London, England, haveinvented new and useful Improvements in or Connected with Non-RefillableBottles, of which the following is a specification.

My invention relates to a stopper for bottles or other receptaclescarrying liquid or semiliquid substances, and has for its object toprovide simple and efficient means for preventing the refilling of anempty bottle, while at the same time permitting of the liquid contentsof the bottle being freely poured out.

According to my invention .I introduce into the neck of the bottle andbelow the ordinary cork a hollow plug or tubular device, which ispreferably cork-covered and tightly fits the bottle-neck and theinterior of which is furnished with a valve adapted to rest upon a seaton or in the tubular plug, through which the contents of the bottle mustpass when being poured out, so that when the said valve is upon its seatthe liquid cannot escape. The valve comprises a valve properthat is tosay, the portion which rests upon the seatingand a trumpetshaped hollowstem connected at one side to the said valve proper and being expandedat the other end. The expanded hollow stem contains a small quantity ofa liquid, preferably mercury, or of a powder--such as iron filings,sand, or the likeor shot of any kind, or a single shot acting as movableballast. IVith this arrangement the mercury or the equivalent in theexpanded valve-stem normally retains the valve upon its seat by itsweight and holds the same in place until the bottle is turned almostupside down-that is to say, into such a position that the said mercuryflows from the hollow expanded head of the stem into the said stem, thusshifting the center of gravity of the valve, which then leaves its seatand permits of the escape of the liquid.

In the accompanying drawings, Figure 1 is a vertical section of abottle-stopper made according to the invention and shown in place withinthe neck of a bottle; and Fig. 2 is a horizontal section on the line 22, Fig. 1.

a is the hollow plug or tubular device of any suitable material, butpreferably ebonite or vulcanite covered with thin cork a,which fitstightly within the bottleneck b in Fig. 1, and c is the valve-seat,which is provided within the hollow plug a.

(Z is the valve, which rests upon the seat 0, and e is thetrumpet-shaped hollow stem, which extends from the under side of thevalve d and terminates at its lower extremity in the expansionf. Thevalve d is weighted with movable ballastsuch, for example, as the liquid9 contained in the expansion The liquid which I prefer to employ ismercury, although I may use in lieu thereof any other liquid of suitablespecific gravity or a powder, such as iron filings or sand, orfinegrained shot or a single shot.

The stopper acts as followsthat is to say, the weight of the mercury orthe equivalent in the expansion f normally holds the valve (1 upon itsseat 0, even if the bottle be placed horizontally, and retains it inthis position until the bottle is turned nearly upside down when thecontents thereof are being poured out. WVhen the bottle is tiltedforward to a considerable inclination, the moving ballast or mercury gin the expansion f runs into the hollow trumpet-shaped stem 6, and soshifts the center of gravity of the valve (1, which therefore suddenlyleaves its seat and permits of the contents of the bottle I) beingpoured out. The moment, however, the bottle is again brought to thehorizontal position the mercury in seeking its level runs down theincline and flows back into the expansion, thereby effectually closingthe valve.

It will be understood that a plug fitted with one of the aforesaidvalves, as illustrated, suffices to render the refilling of an emptybottle very diflicult and tedious without the employment of specialappliances. In order, however, to render it practically impossible totamper with the stopper for the purpose of refilling, I may provide theoutlet a at the upper part of the hollow plug a with a loose cap it,which, while it does not interfere with the pouring of the contents ofthe bottle, yet hinders the insertion of a device, such as a piece ofwire, for mechanically holding the valve (Z from its seat.

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to be performed, I declare thatwhat I claim is 1. I11 a bottle-stopper, the combination with a bellowplug open at one end and provided at its other end with a valve-seat, ofa valve located in the end of said hollow plug, a valve-seat within saidhollow plug, a valve having a-portion adapted to bear upon said lattervalve seat and having a trumpetshaped stem provided with an expandedportion and movable ballast in said stern, said valves being adapted topermit the outflow of the contents of the bottle but adapted to preventfluid from being forced therein, sub stantially as described.

2. In a bottle-stopper, the combination with a hollow plug open at oneend and provi ded at its other end with a valve-seat, of a valve locatedin the end of said hollow plug, a valve-seat within said hollow plug, avalve having a portion adapted to bear upon said latter valve seat andhaving a trumpetshaped stem provided with an expanded portion, movableballast in said stem and lugs in said hollow plug adapted to guide saidstem and limit the movement of said latter valve,

said valves being adapted to permit the outflow of the contents of thebottle but adapted to prevent liquid from being forced therein,substantially as described.

3. The combination with a bottle, of a hollow plug located in the neckthereof, packing between said neck and said hollow plug, said hollowplug being open at one end and pro vided at its other end with avalve-seat, a valve having a portion adapted to bear upon saidvalve-seat and having a stern provided at its end with an enlargedportion provided with angularly-disposed projections adapted to engagethe under side of said valve-seat, a valve-seat within said hollow plug,a valve having a portion adapted to bear upon said latter valve seat andhaving a trumpetshaped stem provided with an expanded portion, movableballast in said trumpetshaped stem, and lugs within said hollow plugadapted to guide said stem and limit the movement of said latter valve,substantially as described.
